introduction

What is ASTM A572 42 welded pipe?
ASTM A572-42 is a high-strength, low-alloy structural steel pipe that is easy to form, machine, and weld.
What is ASTM A572 42 Spiral Steel Pipe?
ASTM A572-42 spiral welded pipe has a minimum yield strength of 50 kilopounds per square inch (KSI) and a minimum ultimate tensile strength of 65 KSI. The presence of niobium and vanadium increases its strength and microstructure, producing a good dispersion of alloy carbides in an almost pure ferrite matrix.
ASTM A572 GR.42 spiral steel pipe is often used in supporting structures, beams, columns, trusses and other components of buildings and bridges due to its high strength and good toughness. Its excellent welding performance makes connection at the construction site convenient and reliable. In the fields of heavy machinery, mining equipment, agricultural machinery, etc., ASTM A572 GR.42 spiral submerged arc tube is used to manufacture components that withstand high loads and impacts, such as shafts, brackets, gearboxes, etc.
